FIELD

The subject matter relates to wireless communications, and particularly relates to a wireless network device.

BACKGROUND

Wireless communication is widespread. An LTE (Long Term Evolution) module for receiving and/or transmitting wireless signals needs to be connected to a power module to obtain a power supply. The LTE module and the power module are generally connected through engagements of bumps and slots. However, the LTE module cannot rotate relative to the power module in this engagement mode. In other words, an angle and direction of the LTE module relative to the power module cannot be adjusted. So the signal strength cannot be improved by adjusting the angle of the LTE module when the signal is not good.

The case 5 can be rotated relative to the rotating seat 22. A free end of the sidewall 222 is substantially necking to fit with the slot 211. The free end of the sidewall 222 is engaged and latched in the slot 211.

The contact point 322 is positioned on the elastic portion 321. The elastic portion 321 includes a combination of two side springs. One of the two side springs is straight, and the other one of the two side springs has a wave-like shape. When the first electrode 71 is rotated along with the LTE module 300 relative to the power supply module 200, the elastic portion 321 will be returned to its original position under an elastic force of the contact point 322, thereby avoiding poor contact between the elastic portion 321 and the first electrode 71.

One of the two side springs is straight, and the other one of the two side springs has a wave-like shape. When the conductive member 34 is rotated along with the rotating seat 22 relative to the fixed seat 21, the contact pin 331 will be returned to its original position under an elastic force, therefore avoiding poor contact of the contact pin 331 and the second conductive part 342.

A plurality of grooves 343 is defined on the first conductive part 341. Each groove 343 extends in a radial direction. The grooves 343 are arranged in a ring on the first conductive part 341. Each contact pin 331 of the negative pole 33 is partly embedded into one of the grooves 343. When the rotating seat 22 is rotated, the first conductive part 341 is accordingly rotated, and the contact pins 331 slide on the first conductive part 341 until entering into the grooves 343. In this exemplary embodiment, an annular portion of the first conductive part 341 which the grooves 343 define is convex towards the negative pole 33, thereby increasing contact area and contact stability of the contact pin 331 and the groove 343.

The first electrode 71 is a metallic plate. The first electrode 71 includes a fixing end portion 711 and a contact end portion 712. The fixing end portion 711 and the contact end portion 712 are opposite and away from each other. The fixing end portion 711 is fixed on the circuit board 6.

In this exemplary embodiment, an end surface of the contact end portion 712 is arced. In this exemplary embodiment, microstructures are formed on the end surface of the contact end portion 712. The microstructures serve to promote and increase contact with the positive pole 32.

Each second electrode 72 includes a fixing part 721 and a contact part 722. The fixing part 721 is fixed on the circuit board 6. The contact part 722 is positioned on a side of the fixing part 721. The two contact parts 722 are located at the two sides of the first electrode 71. The two contact parts 722 are opposite and away from each other. The two contact parts 722 are electronically connected to the two second conductive parts 342.

Referring to FIG. 2 and FIG. 4, the exemplary wireless network device 100 of the present disclosure is assembled as follows:

The button 53 is pressed and the docking part 52 of the case 5 is inserted into the convex portion 224 of the rotating seat 22.

The button 53 is released to let the contact parts 722 of the two second electrodes 72 sink into the two shaft holes 226 and connect to the two second conductive parts 342.

When the signal is poor, an angle of the LTE module 300 relative to the power supply module 200 can be adjusted by swinging the case 5 and/or rotating the rotating seat 22.
